BMW X5 E70 2009 3.0L Oil Leak Under The Car Help NEEDED

[Fasieh55]

Hi, Guys I hope you are all doing well ! I recently went to the mechanic for some exhaust sensor issue and when the car was on the lift I saw that the metal under the oil pan was wet and oily. Its not much of a big leak since there is not so much oil and there is no oil on the floor dripping. No warning on the dashboard. The car runs fine. Attached below some pictures. I cant attach videos. If you guys could help it would mean a lot!!
